JPong for android devices

A simple tennis game in which 2 players can play in multiplayer using
the bluetooth technology. The application can be set as a server, or as
a client which connects to the server. The server sends the ball and
it's paddle coordinates to the client and manages the game rules and the
client sends it's own paddle coordinates to the server. All the data
that is sent is put into an object and then it's serialized as a JSon
string and deserialized for reading.
